range knob to a higher range.
3. Before measuring, LCD display might not be zero, the
residual reading will be decreased gradually and could be
disregarded.
4. When measuring large capacitance, if creeps seriously or
break capacitance, LCD will display some instability
value.
5. Discharge all capacitors completely before capacitance
measurement to avoid damage.
6. UNIT: 1uF =1000nF 1nF=1000pF
3.8 DIODE AND CONTINUITY TEST
1. Insert the black test lead to "COM" terminal and the red
one to "V/Ω" jack ( Note: the polarity of red test lead is"+").
2. Set the range knob to " " range, connect the test
leads to the diode under measured, reading is the
approximation of the diode positive volt drop.
3. Connect the test leads to two points of the measured
circuit, if buzzer sounds, the resistance is lower than
approx. (70±20)Ω.
3.9 TEMPERATURE MEASUREMENT
Insert the cathode of thermocouple’s cold end to " COM" jack
and anode to " mA" terminal, put the working end on or in the
tested object, temperature value can be read on LCD in
Celsius.
3.10 TRIODE hFE
1. Set the range knob to hFE.
2. Insert the test accessory into “COM” and “mA” terminal.
3. Verify the type of the transistor is NPN or PNP, insert the
emitter, basic and collector to the proper jack on test
accessory.
3.11 AUTO POWER OFF

Stop working around 15 minutes, the instrument will auto off
and get into the sleeping mode. To restart the meter, press
